NICHOLLS—COPEPODA FROM SOUTH AUSTRALIA 13 
LApmocera CeRVI Kramer 1895. 
Kramer, 1895, p. 218 ; Brady, 1899, p. 87; Farran, 1929, p. 275; Dakin and Colefax, 
1940, p. 101. 
Occurrence, TI, 1 female (2:60 mm.); TV, 1 male (2°95 mm.) ; V, 1 male 
(2:42 mm.). 
Distribution. Coastal waters of northern New Zealand, and of southern and 
eastern Australia. 
In the female found here the abdomen was distinctly three-segmented as 
pointed out by Dakin and Colefax; the male and female fifth legs agree well with 
those figures by these authors (fig. 148 d, f). 
LABIDOCERA CAUDATA 8p, Nov. 
Occurrence. V, 2 females. 
Female. Length 2-24 mm. The head is rounded and without crest or side 
hooks; the urosome appears to be 2-sezmented but is so completely enveloped by 
the spermatophore that its segmentation is somewhat obseured. The asymmetry

shown by the eaudal rami is unnsual in that the left ramus is larger than the right ; 
there is no lateral outgrowth on the genital segment, which is slightly swollen 
ventrally. The fifth thoracic segment ends in lateral points which are also sym- 
metrical. The fifth legs have a comparatively large endopod, reaching as far as the 
first outer spine of the exopod. The spines on the exopod are none of them very 
large except the terminal spine which is long and sharply pointed. 
This species clearly cannot be identified with that described as sp. (nov.?) by 
Dakin and Colefax, but approaches most closely to gangetica Sewell (1934). I 
have been unable to compare it with rotunda Mori (1929) and japonica Mori 
(1935) as the publication in which the descriptions have appeared is not avail- 
able in Australia.
